Afraid to say it won't. MiniBrute sends Pitch/Gate CV information when the Arpeggiator is running, so you could use MB as an analog arpeggiator source, but it isn't possible to advance MiniBrute's arpeggiator with a gate like you can on a Juno 60 for example. You'd have to physically modify the MiniBrute to add that. You can obviously sync the Arpeggiator to MIDI clock though.

Major disappointment there, but at least the envelope can be triggered from the input, which is extremely useful. I do that often with my Yamaha CS synth to make basic rhythmic bass lines & percussion.
